I opened a support ticket about this and got a text block response that didn't address my problem: Driving the IC 2221 Lübeck-Hamburg and the RE80 11479 Lübeck-Hamburg, there is an AI train stuck inside Hamburg Hbf and not departing it due to an apparently bugged red signal, causing a chain of AI trains stuck at red signals, preventing me from completing the journey as the last train in the chain. Other users have reported this issue (including with other services) here and in my PC discussion forum thread here. Please help, Dovetail, this pretty much breaks the route for me, since the IC has only one service in each direction... The first image is what I suspect to be the bugged signal, the following ones are AI trains queuing up the line, the last one is my RE80. PS: I just wrote a bug report and got no option to attach files. After clicking "submit", I was told that I should consider attaching screenshots next time...
